What does Newton’s first law of motion state?
What does Newton’s first law of motion state?
- A body remains in the state of rest or uniform motion unless acted upon by an external force (correct)
- A body changes its velocity when an external force acts on it
- A body's motion is always affected by multiple forces
- A body in motion tends to stay in motion unless acted upon by an internal force
What does the first law of motion define?
What does the first law of motion define?
- The effect of multiple forces on a body
- The force qualitatively (correct)
- The impact of internal forces on motion
- The relationship between velocity and acceleration
In simple words, what does Newton’s first law imply about a body's motion?
In simple words, what does Newton’s first law imply about a body's motion?
- A body's motion is independent of external forces
- A body will stop moving if no external force is applied to it
- A body will not start moving until an external force acts on it (correct)
- A body will continue moving at a constant velocity without any force
